Android still sucks - still no WPA2 enterprise support!
Are they mad? Are they INSANE?
Even worse my wireless no longer works - their update overwrote my /etc/wifi/wpa_supplicant.conf with a dummy WRITE PROTECTED one so my old wifihelper app (and wifinder) can't write to it.
This means my Motorola Milestone does not work with most common university/corporate networks. My ipod touch seemlessly works. Android developers - I HATE YOU.
Oh, of course, I could ROOT my phone so I could update it myself (or use wifinder again). Pain in the (*^(*^(!
What is so embarrassing is that we teach android at this uni and our students can't connect to the network here - we use UTS-WPA (a WPA2 Enterprise network - simple set up, just use WPA2 + AES for stage one, and EAP = PEAP for stage 2. Just use student/staff number and your email password)
For eduroam, you use EAP-TTLS, and use the PAP (nnnnn@uts.edu.au, password) instead.
SIMPLE EH?

Quality-oriented teaching of programming
Worth reading. I see this all the time too.
Why is there a double hump marks distribution with programming subjects?
This post is a good reason why.

What is your personal organisation style?
Schlenger and Roesch describe five distinct styles to organizing time:
- The Hopper quickly and and frequently switches tasks throughout the day. Hoppers often enjoy variety and like to feel the gratification of completing small tasks, but they may be easily distracted by other people or technology. This is the most common of the temporal organizing styles.
- The Perfectionist Plus seeks excellent performance in every activity, sets very high standards for herself and others, and may have difficulty distinguishing between valuable and less-valuable uses of her time.
- The person who is Allergic to Detail enjoys thinking about the big picture and new ideas, sometimes neglecting smaller details or follow-through.
- The Fence Sitter can see both sides of an issue and thoroughly researches upcoming decisions, both large and small, sometimes to the point of forestalling action.
- The Cliff Hanger thrives on adrenaline, deadlines, and external pressure, but sometimes loses track of all the commitments he's juggling.
Schlenger and Roesch describe five styles of organizing physical space:
- The Everything Out likes to have reminders, mementoes, and project materials in plain sight and within easy reach.
- The Nothing Out prefers to have surfaces cleared off and materials stored away.
- The Right Angler enjoys having things look a certain way, with the appearance of precision.
- The Pack Rat keeps almost everything.
- The Total Slob believes that organizing things is a waste of time that could be spent on creative pursuits.
Chinese spam
But why do they pick on me, not the other ones I am aware of?
If you are a chinese blog-spamster, F*** off!!
Blackboard aka UTS Online - how I hate thee
There are so many websites and blogs (google it) bemoaning the pile of crap Blackboard inc. have written.
Sigh.

App Inventor for Android
Oh dear, does this make us programmers redundant?
Apps for Android made easy - I now see a million iFart applications appearing...
Incidentally, It's amazing how your mind explores links - from this website I got to Kawa, then qexo (Xquery) which then leads back to HTML + JSP vs HTML generation via Xquery (http://www.gnu.org/software/qexo/XQ-Gen-XML.html) ...

Go Ahead: Next generation Java Programming Style
here is a brief summary of style changes recommended:
Final is your new love
No setters
Do not use loops for list operations (hint: Use functional programming style)
Use one liners
Use many, many objects with many interfaces (ie: domain driven design)
Use Erlang-Style Concurrency (huh?)
Use Fluent Interfaces (and Domain Specific Languages)
Data Transfer Objects without setters and getters (yeah, makes your code look simpler)

Too Smart for good?
Enterprise Software Development with Java: Spring and Google vs. Java EE 6
But: Spring and VMware are going to build their own Java universe where they dictate momentum, their 'standards' and more and more the commercial consequences as well. From an Enterprise Java point of view it's simpler. Too many things are called "Spring". And this makes it easy on the first look. You don't have to talk about 30 something specifications but about one big framework. And while Spring and Rod Johnson in particular have been extremely valuable in influencing the direction of Java (2)EE after the 1.4 release to the new, much more pragmatic world of Java EE 5, Spring has also caused polarization and fragmentation. Instead of helping forge the Java community together, it has sought to advanced its own cause. Which is perfectly valid - but should be recognized for what it is. Spring is not necessarily open, is not free, is not a community or even multi-vendor effort. Lock in with Spring is just another type of vendor-lockin. And that is, why it will never be a replacement for Java EE.
But there is another takeaway for the Java community and the owner of Java. The hype around innovative and integrated solutions is a proof for the Java EE universe moving too slowly along. Bring in more flexibility. Have more courage with changes. Find a way to adopt trends faster and support better modularity.

All Your Apps Are Belong to Apple: The iPhone Developer Program License Agreement | Electronic Frontier Foundation
Oh boy. Apple have really made me angry. They are forcing this agreement down our throats.
Here is a partial quote:
The entire family of devices built on the iPhone OS (iPhone, iPod Touch, iPad) have been designed to run only software that is approved by Apple—a major shift from the norms of the personal computer market. Software developers who want Apple's approval must first agree to the iPhone Developer Program License Agreement.
So what's in the Agreement? Here are a few troubling highlights:
Ban on Public Statements: As mentioned above, Section 10.4 prohibits developers, including government agencies such as NASA, from making any "public statements" about the terms of the Agreement. This is particularly strange, since the Agreement itself is not "Apple Confidential Information" as defined in Section 10.1. So the terms are not confidential, but developers are contractually forbidden from speaking "publicly" about them.
App Store Only: Section 7.2 makes it clear that any applications developed using Apple's SDK may only be publicly distributed through the App Store, and that Apple can reject an app for any reason, even if it meets all the formal requirements disclosed by Apple. So if you use the SDK and your app is rejected by Apple, you're prohibited from distributing it through competing app stores like Cydia or Rock Your Phone.
Ban on Reverse Engineering: Section 2.6 prohibits any reverse engineering (including the kinds of reverse engineering for interoperability that courts have recognized as a fair use under copyright law), as well as anything that would "enable others" to reverse engineer, the SDK or iPhone OS.
No Tinkering with Any Apple Products: Section 3.2(e) is the "ban on jailbreaking" provision that received some attention when it was introduced last year. Surprisingly, however, it appears to prohibit developers from tinkering with any Apple software or technology, not just the iPhone, or "enabling others to do so." For example, this could mean that iPhone app developers are forbidden from making iPods interoperate with open source software, for example.
...Kill Your App Any Time: Section 8 makes it clear that Apple can "revoke the digital certificate of any of Your Applications at any time." Steve Jobs has confirmed that Apple can remotely disable apps, even after they have been installed by users. This contract provision would appear to allow that.
We Never Owe You More than Fifty Bucks: Section 14 states that, no matter what, Apple will never be liable to any developer for more than $50 in damages. That's pretty remarkable, considering that Apple holds a developer's reputational and commercial value in its hands—it's not as though the developer can reach its existing customers anywhere else. So if Apple botches an update, accidentally kills your app, or leaks your entire customer list to a competitor, the Agreement tries to cap you at the cost of a nice dinner for one in Cupertino.
Overall, the Agreement is a very one-sided contract, favoring Apple at every turn. That's not unusual where end-user license agreements are concerned (and not all the terms may ultimately be enforceable), but it's a bit of a surprise as applied to the more than 100,000 developers for the iPhone, including many large public companies. How can Apple get away with it? Because it is the sole gateway to the more than 40 million iPhones that have been sold. In other words, it's only because Apple still "owns" the customer, long after each iPhone (and soon, iPad) is sold, that it is able to push these contractual terms on the entire universe of software developers for the platform.
In short, no competition among app stores means no competition for the license terms that apply to iPhone developers.

Oracle purchases Apache foundation
Tsk tsk tsk.
Apparantly Oracle will change the Apache Software Licence (ASL) to the Apache Full and Open Oracle License (AFOOL) :-)

David Siegel discusses the Power of Pull; a different view of the Semantic Web? | The Semantic Web| ZDNet.com
Siegel wrote books such as Futurize Your Enterprise and Creating Killer Websites (both impressive books, though at a view from 10000 feet).
In his new book "Pull: The Power of the Semantic Web to Transform Your Business" he suggests that using Semantic Web (though not just W3c technologies such as OWLS, RDF SPARCQL) can be the savior for web enabled businesses (and those who aren't :-)
What IS interesting is that Google are in an indirect way doing this - "PULLing" past information to make interesting deductions for the present. It's sometimes spooky how their data mining algorithms work - check the advertisements displayed from gmail.

motorola milestone - finally rooted
(since I have a british milestone from expansys.com.au, it gets its update from europe motorola via the internet),
Menu -> Settings -> System Updates ... & it runs for while....
When complete, you can now root.
Follow instructions from http://news.lehsys.com/?p=7537
1. download http://rapidshare.de/files/49019165/milestone_root.zip and rename to /sdcard/update.zip
2. switch off phone
3. hold camera button. Then power on.
4. When you get the triangle screen, release the power & camera button
5. Now tricky bit: Press Volume+ button & camera simultaneously. I had to attempt this about 10 times to get it to work
6. Now you get a list of options - Open the keyboard, use the navigation pad to select "Update from SD card."
7. Use the centre pad key to select - what ever you do, don't choose the "Format SD card" or "Hard Reset" options!!
8. You should see an updating screen - this may have an error message, but as long as you see the message "Rooting phone" (or similar :-), it has worked
9. Reboot the phone
10. Assuming it all booted up & you get your normal phone scree, start a Terminal emulator (I used ConnectBot or "Android Terminal Emulator (Jack Palevich)" from the Android Market, others use "Terminal Emulator" but this gives me the dreaded Force Close message)
11. Type su to get root access!!! ps: Android throws up a big screen "The following application has requested Superuser access to the phone". Select Yes.
ps: sometimes su hangs. I have to restart the terminal emulator to get it working again.
now for linux tools for android: http://android.modaco.com/content/htc-hero-hero-modaco-com/299984/linux-tools-coming-to-mcr/ & http://alldroid.org/threads/16201-HOW-TO-Root-Extras-Telus-Motorola-Milestone

Axis2: Why bother?
Bit harsh but very true - axis2 is not really a usable system. Sun's metro stack is way better. Just trying to get axis2's wsdl2java working resulted in me breaking a tooth in anger.
What get's my goat about Eclipse is it's linkages to Apache - the Web Tools Project webservices stuff deals only with Axis and it's ilk.
Oh yeah, there is a new Apache CXF interface which at least implements a marginally better product. But just check out the predic8 blog entry: http://www.predic8.com/axis2-cxf-jax-ws-comparison.htm
I'll quote it here for your reference:
WS-* Standards
| Standards | Axis2 | CXF | JAX-WS/Metro |
|---|---|---|---|
| WS-Addressing | X | X | X |
| WS-Coordination | X(2) | X | |
| WS-MetadataExchange | X | ||
| WS-Policy | X | X | X |
| WS-ReliableMessaging | X(3) | X | X |
| Web Services Security | X(1) | X(4) | X |
| WS-SecureConversation | X(1) | X | |
| WS-SecurityPolicy | X | ||
| WS-Transaction | X(2) | X | |
| WS-Trust | X | X | |
| WS-Federation |
(2) Supported by the additional module Apache Kandula2
(3) Supported by the additional module Apache Sandesha2
(4) By Apache WSS4J Interceptor
Another post is: http://www.arobs.com/innovationtech/tag/axis2-vs-cxf-vs-metro/ ps: this seems to be mostly a cut and paste from Thomas's blog... mmm ggrr.
And also: http://srikanthnukala.net/devblog/2009/06/29/axis2-vs-jax-ws-vs-apache-cxf-vc-spring-ws/
My problem is that Eclipse only supports the Apache products with the web services client generator.
Bugger them.
